' of this specification.

This invention relates to au improved ice- Y cream freezer; and itconsists in the certain details of construction and combination ofparts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1'is a side central sectionalelevation of my vimproved ice-cream freezer, the same being constructedand arranged in accordance with my invention. Fig. 2 is a plan view ofaportion of the same. Fig. 3 is a sectional plan view of the dasherdetached from the freezer, the said dasher being fitted with a scraperarranged to adjust itself to the side of the can during the rotaryInovementof the same. Fig. et is a detailed side elevation of one of themeans attached to the side of the tub for holding the frame in position.Fig. 5 is a side elevation of the means for attaching the other end ofthe supporting-frame to the tub.

To construct an ice-cream freezer in accordance with my invention, thesame consisting of the tub 1, the freezing-can 2, the lid or cover 3 forthe same, together with other well-known features common to an apparatusfor this purpose, I arrange across the top of the said tub l a frame 5for the purpose of supporting the mechanism for rotating or revolvingthe freezing-can 2 and its inclosed dasher 25. This frame consists of ametal plate one end 10 of which is forked to engage with openings 12,formed in a plate 11, attached by wood-screws 13 to the upper side ofthe tub 1, as shown at Figs. 1 and 4 of the drawings. The other endofthe plate or frame 5 is formed with notches 6, one'at either side, andthe said notches adapted to engage with two hinged pieces 7, attached byscrews 8 to the side of the tub 1 and formed at the top withscrew-threads upon which the thumb-nuts 9 are placed. These thumb-nuts9, together with the plate 11, afford a means serial'ro. 49,471. (Noman.)

of rigidly attaching the frame 5 to the top of the tub 1. Mounted insuitable bearings 16, formed with the frame 5is a shaft 16', fitted atthe one end with a hand-crank 17 and at the other with a small pinion15. This pinion 15 is in mesh with another,14, attached to the top ofthe freezing-can 2, and is also in mesh with a pinion 18, arranged uponthe top of the dasher-shaft 24. This pinion 1S, last mentioned, isformed integral with a bevel-wheel 19, geared to a shaft 22 bya pinion20. This shaft 22 incloses the firstmentioned shaft 16', and is fittedwith a ily-wheel 23. Arranged in the interior of the can 2 is a dasherand scraper, the dasher consisting of a series of vertically-arrangedangular bars 25, capable of a rapid rotary movement by means of thegearing above mentioned, and' is supported in a bearing 29 at thebottoni of the can, and its shaft 24 supported in the frame 5 above.Arranged at one side of the dasher above described is a scraperconsisting of a bar 26, formed with a sharpened edge and the said edgekept in close contact with the side of the can 2 during the rotarymovement of the dasher. This scraper 26 is attached to the dasher bypins operating in slots 27 in a manner to permit alimited in; and outmovement, and the said scraper backed by springs 28 to hold the saine eXtended.

In operation the parts are arranged as shown at Fig. 1 of the drawings,and by power applied to the crank 17 the can 2 is rotated in onedirection and the dasher in another, and the scraper 26 being at alltimes in close contact with the sides of the can will IOO Will keep thesaid scraper in close Contact the same to the top of the tub, allarranged with the side of the can, the pinion 14 atfor service, asdescribed.
